Abstract

La présente invention concerne un ruban adhésif, notamment un ruban pour câbles, comportant un substrat pourvu, au moins sur un côté, d'une couche auto-adhésive composée d'un adhésif sensible à la pression. Pour obtenir, en générant moins de dépenses par rapport à l'état de la technique, que le ruban adhésif présente une plus grande résistance à l'abrasion tout en conservant ses propriétés conformes aux exigences, en particulier son aptitude à être travaillé manuellement et mécaniquement qui est liée au comportement de décollement, il est prévu d'agencer, entre le substrat et la couche auto-adhésive, une couche intermédiaire et/ou, sur le côté du substrat opposé à la couche adhésive, une couche supérieure comprenant un liant dans lequel sont incorporées des particules dont la taille se situe dans la plage allant de 0,010 µm à 30,00 µm.
